All voltage is ground standardised.

Note :

Please ensure that the sum total of power used within the IC does not exceed the

continuous total power dissipation (Pd) figure.

The figure for total continuous power dissipation ( mounted ) represents the

value when tested on a single sided glass epoxy board of dimensions :

21mm x 32mm ; t = 1.6mm
